Of course I have. If I see ghostty constantly consuming the most energy and helping reduce my battery life to barely 2 or 3 hours, the first thing I'm going to do is switch terminal to see if I can improve that situation. The built in terminal and WezTerm have been fine and I've had much more reasonable battery life since.

This does not even speak to it pegging my CPU and keeping the fans running on full blast even when the laptop is supposed to be idle overnight.

This seems a suspicious. How do you measure the CPU load of Ghostty? Is the measure/reporting method just attributing the cpu load of the commands/programs you're running in Ghostty to Ghostty?

You could test this by running "yes > /dev/null" in Ghostty. In Activity Monitor on my Macbook it shows `yes` using 100% and Ghostty using 0.5% of cpu.

If you're looking for a non-ghostty recommendation (not that I have anything against ghostty) I use alacritty + zellij and it works fantastic. It doesn't seem to impact battery, I certainly get good battery usage on both my work and home laptops.

Same. I really want to file a proper bug report for this but I haven't been able to really dig into the details and the last thing I want is a "ghostty is a cpu hog" kind of report without useful info on how to debug that.
